Disposal
The following excerpt was taken from the Congressional Research Service Report Federal Land Ownership: Current Acquisition and Disposal Authorities.

"The [National Park Service] does not have general authority to dispose of National Park System lands. Units and lands of the Park System that were established by Acts of Congress can only be disposed of by Acts of Congress. Preservation of park units is a management goal and several laws limit the power of the Secretary of the Interior to change park boundaries.  Non-NPS lands encompassed by minor boundary adjustments can be acquired through land exchanges, but 'the Secretary may not alienate [dispose of] property administered as part of the national park system in order to acquire lands by exchange' (16 U.S.C. § 460l-9(c))."

"Presidents have modified the boundaries of national monuments established by previous presidential proclamations, in some cases reducing the size of the monument. However, no president has terminated a monument established by proclamation. Further, national monuments proclaimed by a president cannot be returned to the public domain for disposal under the [Bureau of Land Management] land disposal authorities.  Specifically, 'The Secretary shall not ... modify or revoke any withdrawal creating national monuments under' the Antiquities Act (43 U.S.C. § 1714(j))."
